Deciduous forests, swamps, and river-bank thickets. Southern Michigan is at the northern edge of the range of this species. The Upper Peninsula record was spread from plantings.
A very few specimens have sparse stipitate glands on the pedicels, interpreted as being suggestiive of introgression with Aesculus flava (and some specimens thus determined as A. flava × A. glabra). But any influence of A. flava is presumably negligible; such specimens otherwise seeming like typcal A. glabra in morphology and ecology.
Aesculus glabra is the earliest native tree to leaf out, and may bloom as early as April.
